Airsal brings us the 50mm Xtreme kit for AM6 powered bikes with the stock stroke crankshaft. 78.5cc is sure to deliver some serious power. The AM6 is found on several bikes including Rieju RS3, Aprilia RS50, some Yamaha TZR50, and more.
This cylinder is very impressive. Split exhaust port and auxiliary exhaust ports. High quality Vertex piston features a single ring design and coated dome. This is probably best suited for the experienced tuner.
Comes with everything pictured. Cylinder, piston, ring, pin/clips, head, exhaust spacer, brass fittings, and gasket kit.
